This patch clarifies the definition of google_chromeec_command.
Currently absence of the definition isn't causing any problem because
wrapper APIs check 'ret != 0' or wrapper APIs check 'ret < 0' for an
interface which returns only negative error codes.
However, there is a chance that a new wrapper API will be addedl which
check 'ret < 0' to catch errors, assuming other interfaces behave the same.
Or existing wrapper APIs will be broken as soon as they're compiled for
another interface.

This driver is used in Windows and in the Linux kernel at

define the SMBIOS enclosure type as convertible for the check at

EC_SYNC_IRQ from EC to host is level-triggered in practice and
configuring it as edge-triggered on the host results in host missing
events if there are multiple events queued on the EC side. This is
because Linux kernel driver reads one event per irq and the EC does
not de-assert the interrupt line until all events are drained
out. This results in event queue being filled up completely on the EC
and the host failing to see any of those events.

If remaining charge is more than x% of the full capacity, the
remaining charge is raised to the full capacity before it's
reported to the rest of the system.
Some batteries don't update full capacity timely or don't update it
at all. On such systems, compensation is required to guarantee
the remaining charge will be equal to the full capacity eventually.
On some systems, Rohm charger generates audio noise when the battery
is fully charged and AC is plugged. A workaround is to do charge-
discharge cycles between 93 and 100%. On such systems, compensation
was also applied to mask this cycle from users.
This used to be done in ACPI, thus, all software components except EC
was able to see the compensated charge. This patch is part of the
effort of moving the logic to EC. With this and the EC changes, EC
can see what the rest of the system sees, thus, can control LEDs
synchronously (to the display percentage).
Another rationale of this move is EC can perform more granular and
precise compensation than ACPI since it has more knowledge about the
battery and the charger.

The EC RAM address space is typically read/write, and so the ACPI EC
device expects that a defined Field can be read and/or written. With
this EC the read and write address spaces are different. For example,
a read from address zero will return data that is unrelated to what a
write to address zero expects.
This makes using a typical OperationRegion to describe the EC RAM
address space somewhat impracticle, since field definitions would
overlap. Instead, methods are provided for reading and writing to an
EC RAM offset, and the EC RAM layout is defined as a Package that
describes offset+mask for read or write fields within the EC RAM.

Add a chip_operations structure for Wilco EC and hook it into the device
tree so it can be initialized at boot.
Reserve the device resources specified in Kconfig, which will also
create the device IO windows if they have not been created in bootblock.
If the IO windows already exist (becauase they were specified in the
mainboard devicetree.cb) then this will find the existing entry instead.
During device init stage prepare the keyboard for use, which is required
for it to be functional in firmware and OS with this EC. Also send a
command to the EC telling it to pass the power button through to the
host for processing.

The Google "Wilco" Embedded Controller is a new embedded controller that
will be used in some future devices. The mailbox interface is simliar
to the existing Chromium EC protocol version 3, but not close enough
that it was convenient to re-use the full Chrome EC driver.
This commit adds the basic mailbox interface for ramstage which will be
used by future commits to send varous mailbox commands during the boot
process. The IO base addresses for the mailbox interface are defined in
Kconfig so they can be changed by the mainboard if needed.

Some boards are adding a second pin used for synchronization between
the EC and AP. This is a direct connection between the EC and the SOC
that is intended to provide a lower latency interrupt signal for
sensors on the EC.
Currently the runtime EC interrupts assert an SCI before eventually
resulting in a Notify() on the MKBP device that the sensor driver users.
These extra layers add processing time and require additional EC
communication to determine the event source.
This interface was tested on a reworked Nocturne board with modified
EC and a modified kernel driver to ensure that the interrupt asserts
as expected and can be used by the kernel driver.

Currently the throttle event handler method THRT is defined as an extern,
then defined again in the platform with thermal event handling. In newer
versions of IASL, this generates an error, as the method is defined in
two places. Simply removing the extern causes the call to it to fail on
platforms where it isn't actually defined, so add a preprocessor define
where it's implemented, and only call the method on those platforms.

This maps a bit field to the EC (EC_ACPI_MEM_USB_PORT_POWER) that can be
used to control the power state of up to 8 individual USB ports. Some
Chromeboxes have their GPIO pins for controlling USB port power wired to
the EC, so they cannot be accessed directly by coreboot.

The tablet event handler method TPET is defined as an extern, then
defined again in skylake, the only platform that supports it. In newer
versions of IASL, this generates an error, as the method is defined in
two places.
Remove the extern and the CondRefOf check. That's not needed if we
only set the EC_ENABLE_TABLET_EVENT define on platforms that have a
TPET handler.

Currently, google_chromeec_pd_get_amode infinitely loops if a TCPC port
is connected to a device with alternate mode(s) and the call is made
for the mode with the index higher than 0 (e.g. Zinger).
Cros EC manages alternative modes entered in an array (amode[]). The
command is designed to accept a query for an particular index and a
particular SVID.
Zinger has a 'Google' mode. It's stored in amode[0]. When AP queries
first time for DisplayPort with index=0, EC says 'no' as expected.
AP sends the next query with index=1 but EC_CMD_PROTO_VERSION (0x00)
is sent instead because cmd_code is cleared by google_chromeec_command.
res.svid is supposed to be 0 when EC hits the last index + 1 but
res.svid is set to 2 by the EC_CMD_PROTO_VERSION handler because
EC_PROTO_VERSION is currently 2. So, the call succeeds and AP goes to
the next index and this repeats forever.
Any USB-C device with non-DisplayPort alternate mode can cause this
hang unless HDMI port is used.
This patch resets all the fields of chromeec_command in each iteration
in case google_chromeec_command changes them.

Some type-c monitors do not immediately assert HPD. If we continue
to boot without HPD asserted, Depthcharge fails to show pictures
on a monitor even if HPD is asserted later.
Also, if an HDMI monitor is connected, no wait is needed. If only
an HDMI monitor is connected, currently the API always loops until
the stopwatch expires.
This patch will make the AP skip DisplayPort wait loop if it detects
an HDMI monitor. And if an HDMI monitor is not detected, the AP will
wait for DisplayPort mode (like before) but also its HPD signal.
This patch also extends the wait loop time-out to 3 seconds.
